WHIFFLETREE-HOOK.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed April 27, 1914. Serial No. 834,723.

To all whom it may concern:

Be it known that I, J AMES MGCLELLAND, a citizen of the United States,residing at Carson City, in the county of Montcalm and State ofMichigan, have invented a new and useful IVhiflletree-Hook; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improved Whittle-tree hook.

It is an object of the present invention to simplify, improve and rendermore efficient, the construction of the whiflle-tree hook patentedJanuary 1, 1907, No. 840,152, in the name of James McClelland.

One of the features of the invention is to construct the cuff of thehook with a pair of lugs, instead of the rib 7 in said patent, andbetween which lugs one of the jaws of the whiffle-tree hook is pivoted,said lugs being braced or reinforced relative to the stationary jaw ofthe hook by means of a short bar, thereby affording a more rigid andfirmer substantial structure than disclosed in said patent.

Another feature of the invention is that the stationary jaw has asegmental rib, partially overlapping the pivoted jaw, and together withthe stationary jaw acting to withstand all the strain and draft.

In practical fields the details of construction may necessitatealterations, falling within the scope of what is claimed.

The invention comprises further features and combinations of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :-Figure 1 is a perspective view of one end of aWhittle-tree with the improved hook fastened thereon. Fig. 2 is asimilar view showing the hook open. Fig. 3 is a sectional view on line3-3 of Fig. 1. Fig. 4L is a sectional view on line 4-4 of Fig. 1.

Referring more especially to the drawings, 1 designates a whiftle-tree,the end of which is cut away, as shown at 2, forming a shoulder 3 andleaving a contracted portion 4, which is inserted in the hollow cufl' orcup shaped casting 5, said casting being held on the whiffie-trec end bythe screw 6. Located on the circumference of the casting is a pair ofcars or lugs 7, through which a pivot pin 8 extends. Pivoted upon thepin 8 is the pivoted whiflle-tree hook member 9 having the curvedportion 10, which registers with the curved hook portion 11 of theimmovable whiflle-tree hook member 12, which is made integral with thecuff casting 5. The whilile-tree hook member 12 is braced or reinforcedrelative to one of the lugs 7 by the bar 1.3. The curved hooked portion11 is provided with a segmental lip or rib 14, which partially overliesthe curved hooked portion 10 of the pivoted member 9. This lip or rib 14together with the curved hooked portion 11 of the stationary member 12withstands the strain or draft entirely. thereby relieving all thestrain from the pivoted member. Projecting upwardly from the movablejaw, and downwardly from the extremity of the hooked portion 11 of thestationary jaw are lugs 15 and T16, constituting means for preventingthe ring of a trace from accidental displacement.

The invention having been set forth, what is claimed as new and usefulis A Whittle-tree hook comprising a cuff shaped casting, a jaw formedintegral therewith, and terminating at its outer portion in a curvedhook, a pair of spaced apart lugs formed integral with said casting, abar formed integral with one of said lugs and integral with said jaw,thereby reinforcing and bracing said lug and jaw, a second jaw pivotedbetween said lugs and having an outer curved hooked portion, adapted toregister with the curved hooked portion of the first jaw, said curvedhooked portion of the first jaw having an integral segmental lipoverlying the curved hooked portion of the pivoted second jaw.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
